Am I correct in assuming that the term leaky promoter refers to promoters
that still drive mRNA production albeit a lower level even when not
stimulated. In the eucaryotes, I seem to always see the term used with
respect to the expression of proteins normally considered to be specific
to one tissue being expressed in anoother tisse at much lower levels.  Can
a leaky pomoter also be described as some procaryotic promoter?
